Sheldon: Hello, Amy Farrah Fowler. I'm sorry to inform you that you've been taken in by unsupportable mathematics designed to prey upon the gullible and the lonely. Additionally, I am being blackmailed with a hidden dirty sock.Amy: If that was slang, I'm unfamiliar with it. If it was literal, I share your aversion to soiled hosiery.

Wolowitz: Okay, what if I were to tell you, tomorrow at 4:30, you could meet a woman who has been scientifically chosen to be your perfect mate?Sheldon: I would snort with derision and throw my arms in the air, exhausted by your constant tomfoolery.

Sheldon: Why do you have the Chinese character for "soup" tattooed on your right buttock?Penny: It's not "soup," it's "courage."Sheldon: No it isn't. But I suppose it does take courage to demonstrate that kind of commitment to soup.Penny: How'd you see it? You said you wouldn't look.Sheldon: Sorry. As I told you, the hero always peeks.
